Application filed April 10, 1909. Serial No. 489,120.

To all whom it may concern:

'Be it known'thatI, WALTER W. SENN, a

of Munson Station, in the'eounty of Clearfield and State ofPennsylvania, have made certain new and useful Improvements in-Nut-Locks, of which: the following is a specification.

This

invention is an improvement in nut object to prov1de a 1 novelconstruction which will be inexpensive and will efliciently serve thepurpose for 1 which it is designed, and which can be used to lock thenut positively on the bolt and-in the use. of which the locking devicescan be readily adjusted to unlocked mit the turning of the nuton thebolt without injury thereto when desired to turn the nut farther on thebolt, or d the bolt .if so desired; and theinvention consists incertain'novel constructions and combinations of parts as will behereinafter described and claimed.

' In the drawing Figure 1 is a sectional side view of my invention as inuse.

Fig. 2' is. an

end view thereof. Fig 3is a detail perspecvided. with-a number tive Viewof the nut, and Fig. 4 is a cross section of the bolt. I

Thebolt A, may in general respects, be of ordinary construction, but isshown proof longitudinally V- shaped grooves A, extending across itsthr'eads,any suitable number of the grooves being" employed. 1.35

The nut B is'in general respects, ofordinary construction and may be ofany suitable metal, such for instance as metal. from which wire nailsare made so the parts to be bent as hereinafter'described may be readilybent into and out of locking position without breaking.

' In the. outer face B of the nutand formed integral therewith arelooking tongues C Whose outer ends are'integral with the body of the nutand whose inner-ends extend into thebore B of the nut'to enter thegrooves .A in the belt or to form such grooves or seats in a bolt shouldthe latter not be pro- The tongues orspurs C are of a specialconstruction tapervided with the grooves.

ing from their outer to their inner ends converging on theirouter sidesat'C' toward the center, while the under faces at 'O of.

the tongues or spurs are sloped gradually {eercasingin thickness towardtheir outer ends so that they are'of-amaximum th ck States, and. aresident position to per-.

unite with-the body. of the ness at their inner ends or points Cflthusaffording a greater strength at suchends,

to the locking operation standclear of or.

outside of the line of the bore B of the nut so thatthe nut may boltwhen the spurs are as indicated in dotted lines, Fig. 1,. and as shownin full lines Fig. 3, and when the nut has been turned home the spursare curved outwardly from the face B of the nut and may be hammered inby any suitable tool-to the full line position shown in Figs. 1 and 2,with their inner ends or points engaging the bolt and locking the nutfrom turning. In forming the spurs C corresponding recesses. areproduced at B in the outer face B of the nut B and are in communicationwith the bore B of the nut. To facilitate releasing the spurs ortongues, I provide slots B extending laterally from the recesses B aboutmidway between the ends thereof and adapted to receive a suitable punchor other instrument by which the tongues may be bent or readjusted fromthe full line position shown in-Fig. 1 to the dotted line positionindicated in. the same figure, when it'is desired to release the nutfrom the bolt.

The construction is simple,

ing the nut, and provides the entire nut, boltand locking devices in thetwo'parts as shown and before described.

I claim- 1. In a'nut lock the combination of a bolt having longitudinalgrooves crossing 'lts threads, a nut having a bore-to receive said boltand provided in its outer face with a series of integral tongues orspursformed from the body of the nut and tapering from their outeroppositesides converging toward the inner ends' or points of the sides"and made of a maximum thickness at their inner pointed ends andgradually reducing in thickness thence toward their outer ends wherethey nut, the spurs being seated when in locked position incorrespondingrecesses in the outerface of the nut, andthe said nutbeing-provided 'in its said outer'face with lateral. slots communicatingwith said recesses and {adapted to reare bent in operation.v

inexpensive, "avoids any separate attached parts for lockto .their innerends with their.

ceive punches or other suitable instruments its outer face by which thetongues or spurs may be readjusted to normal position, substantially asset forth.

2. A nut having a bolt opening and provided in its outer face with aseries of integral tongues formed from the body of the nut and taperingfrom their outer to their inner ends with their opposite 'sidesconverging toward the inner ends or points of the sides and made ofmaximum thickness at their inner pointed ends and gradually reducing inthickness toward their outer ends where they unite with the body of thenut, the tongues being seated when in locked position in correspondingrecesses in the outer face of the nut, and the said nut being providedin its said outer face with lateral slots communicating with saidrecesses and adapted to receive a punch or other suitable instrument bywhich the tongues may be readjusted to normal position.

3. A nut havin a bolt 0 enin rovided D P 2: P

tongues or spurs formed from the body thereof and tapering from theirouter to their inner ends and seated when in locked position in recessesin the face of said nut,

. said nut being provided in its said face with 30 lateral slotscommunicating with the recesses and adapted to receive a punch or vother suitable instrument by which the tongues may be readjusted.

4:. A nut having a on its outer face with tongues, and with recessesreceiving the tongues whereby the tongues may be pressed when in lockedposition into the recesses with their outer faces flush with the of saidnut being slotted alongside the tongues to, facilitate the readjustmentof the tongues, substantially as set forth.
